Specification of Letters Patent.

Annlication filell June 22, 1906. Serial No. 322,870.

To all whom it may concern.-

Be it known'that I, JACOB R. ELFRETH, a citizen of the United States, residing in the city and county of Philadelphia, State .of

Pennsylvania, have invented a new and useful Device for Supplyinga Filter or other,

Receiver with Chemically-Treated Fluid, of which the following is a specification.

My invention relates to a device for supplying a filter or other receiver with chem-, ically-treated fluid; and it consists in providing the pipe which supplies said filter or recelver with unfiltered water or fluid, with means for causing a quantity of such water-to enter achamber which contains a coagulant or chemical or purifying material, so as to be impre nated with a certain quantity of said' material, in which condition it is caused to rejoin the water running to the filter or re ceiver, and so act on the latter to purify it:

Figure 1 represents a vertical section of a chemical feeder for purifying water or fluid embodying my invention. Fig. 2 represents a partial plan view and partial horizontal section thereof. I

spending parts in the figures. f

Referring to the drawings, A designatesa tank or vessel adapted to contain a coagulant or chemical or other materialadapted to purify or treat water or other fluid. Connected with said vessel is the water-supply passage or tube B, whose inlet G is adapted to be connected with asource of supply of water or fluid in primary condition and whose outlet D is adapted to be connected with a filter or other receiver.

Depending from the top of the vessel A is the by-pass E, which is in communication with the passa e B and has in its inner side the seat F for the valve e, the stem of which passes throu h the wall of said vessel and is provided wit a handled wheel H, said seat opening into the vessel A.

Depending from the to of said vessel is the discharge-tube J there or, the same being in communication with the interior thereof and with the passage B. Depending also from said top is the boss K, whose bore is threaded and has engaging with it the screw L, whose head enters the passage Bv and forms in a measure an obstruction to the flow of the water orfluid therethrough;

The construction of the top of the vessel A 4 is such that the portion of the same below the passage B constitutes the underwall of said passage, said parts being cast together, although,-as is evident, the passage B may be formed separate from the vessel A and connected therewith in any suitable manner.

The operation is as follows: Water or fluid in normal condition is admitted into the passage B and the valve G opened to the required extent relatively to the amount of fluid that inay be desired to enter the vessel A. The

screw L is also adjusted to the required height, so asto present itself in the path of the running water in the passage B, so that a ortio'n ofthe same im acts itself against the ead or u per part of t e screw, or both, said portion t us being obstructed and checked I and directed backwardly, so as to flow into the by-pass E, from whence it passes through I the valve and enters the vessel A, where it mingles with'the coagulant, chemical, or

other material to purify or treat the water or fluid and is im regnated by the same. then escapes t ough the tube J, and so reaches the passage B in front of the screw L, where it joins the running water and mixes therewith, in which condition the water en- 2 Similar letters of reference indicate correters the filter or the other vessel to which it may be directed.

It willbe seen that the water or fluid when The said valve being on thedepending boss within the vessel admits of guickly turning on and cutting off the liqui at the vessel,

and yet the untreated water may run through the passage B, if desired. The valve B and the retarding device L are entirely independen}; of each other and-independently operab e.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is V 1... In adevice of the character stated, a vessel adapted to receive a coagulant, chemical or purifying material, a conveyer or way for water or other fluid to a place of reception ada ted to be laced in communication with sai vessel, a 'scharge-pipe depending Within the vessel and communicating with said Way, said vessel having a filling-o ening, and means in said Way for retarding t e flow of a portion of said water or fluid entering said way and directing or diverting a certain, definite predetermined amount of said Water or other fluid into said vessel, said depending tube and retarding means both being accessible through said filling-opening.

2. Ina device of the character stated, a

vessel adapted to receive acoagulant, chemical or puri'fyin material, a conveyer or way for water or 0 er fiuidjto a place of reception adapted to be laced incommunication with said vessel, a ischarge-pipe depending within the vessel: and communicating with said Way, said vessel having a fillin opening, means in said way for retarding t e flow of a portionof said water or fluid entering said way and directing or diverting a certain definite, redetermined amount of said W81: ter or otiier fluid into said. vesselfsaid depending'tube and retarding means bothbemg accessible through said filling-opening, a bypass l'rom. said way to said vessel, and a valve inde endent of said. retarding means and locater within saidvessel.

3. In a. device of the character stated, a vessel adapted to receive a coa ulant, chemical or other purifying material and having formed inte ral therewith a curved way for water or other fluid, a discharge-pipe depending within said vessel and communieating with said way, an adjustable retarding device supported Within the vessel and extending into said Way, a by-pass intermediate of the entrance end-of the conveyor and the vessel and located within the latter, and a valve disposed within the vessel. and indeendent of. said retarding device for controling the outlet from said by-pass into the vessel.

4. In a device of the character stated, a vessel adapted to receive a coagulant, chemical or other purifying material andhaving formed integral therewith a. curved way for water or other fluid, adischarge-pipe depending withinsaid vessel and communieating with said way, an adjustable'retardpassage said device being I the vessel and located within the latter, and

a valve disposed within the vessel and independent of said retarding device for controlling the outlet from said by-pass into the .vessel, said valve being disposed Within the vessel outside of said way and operable 1n' dependently of the retarding device.

5; In a device of the character stated, a-

vessel having a filling-opening, a conveyer for a liquid adapted to be placed in communication with said vessel, a valve Within the communication between saidvessel and conveyer and outside of said conveyor, an adj ustable device in said conveyer for retarding the flow of. liquid entering said conveyer and directing or diverting a certain predetermined amount of said liquid into said vessel through said communication the head of said device being accessible through said opening, and an outlet from said vessel into said conveyer. upon the opposite side of said 'retarding device. v

6 In a device of the character stated, a vessel formed with a supply-passage, a depending tube leading therefrom intothe vessel, a retarding device in said passage, a bypass independent of said tube, and a valve in saidby-pass within the vessel and out of said adjustablysupported on the base-wall of said passage inter mediate of the ends thereof and having its head occupying part of said passage.

7. In a device of the character stated, a vessel formed with. a. supply-passage, a depending tube leading therefrom into the vessel, a boss integral with said tube within the vessel, a retarding device in said passage and adjustable in said boss, a. by-pass independent of said tube, and. a valve 1n said-bypass, within thevessel and out of said passage.
